Hi all,

I have recently purchased and got my TCB running and installed in my HL Challenger 2.
I am using an FrSky QX7 and X4R-SB for communication.
For power i have a 2S 4000mAh LiPo.
I am using some cheapy 10A RC car ESC's off amazon for drive motor control, no big issues with them.

I have the main drive and turret drives all working great, nice smooth operation.

I then went through and started getting the accessories working.
First thing i did was hook up the headlights to the Light 1 port on the TCB and assign the on/off to a couple positions on my transmitter
When I snooped the board, i saw that the trigger was being processed correctly, however when i connect the LED's they are always on??
I tried them in the Light 2 port and re-assigned the on/off to that
Again snoop indicated that it was trying to turn the lights on and off correctly, but again they never turned off.

At this point i just unplugged them and moved on to the airsoft unit
I re-wired the stock airsoft unit to match the wiki instructions and youtube video
I went through and assigned the cannon fire command to a momentary on my transmitter
I double checked the snoop output and it appeared to be reading the command correctly

I then proceeded to connect the airsoft unit, it fired, then just kept firing.
I read through the post by Lotuswins regarding airsoft issues.
I tried a number of things to get the airsoft unit to NOT fire when the board was powered up, no luck
I tried enable/disable airsoft, i tried unchecking trigger with cannon, nothing seems to stop the power to the unit.
I also tried using a pair of pliers to short the trigger switch contacts together, no luck.

I did a quick visual inspection of the board to check for solder bridging or obvious flaws, but i found none.

If anybody has experienced anything like this, or had any advice please let me know.

Thanks,
Brad
